Hi John, I've put a few up now, if they keep doing well I may post some more! I haven't quite found the shot I want online yet, so may have to get out the external drive and use some my daughter and I have taken.

Fabulous! Go to Google Images, search on "erosion Utah" - there are several that look very similar. The US West has some breathtaking geology - John you've given me the idea to look for some good photos of Red Rocks Amphitheatre.
